Make a USB Color Changing Light
Everybody needs a little color in their life! This color changer mixes light from high-power LEDs to create more than 16 million colors. A smooth auto-fader cycles the colors, or you can hook it up to a USB port and control it from your computer. A great toy for architectural lighting, parties, and holidays. Since the circuit will run from 12 volts, it can even be installed in a car.
